y Be it known `thatI, DAvm RUSSELL, of

Drewersburg,` in the county of Franklin,

p. inthe State of Indianahave invented a new and useful `Improvement in iSt-raw` Cutters;` andIydohereby declare that the following is a full and exact description of the same, reference being had to the accomf panying drawings and to the letters` of reff.

erence marked thereon, like letters referring `"to` like parts of the machine.

Figure 1 is afa ce eleva-tion. Fig. 2 is a To enable @there skilled in the are to make, and use my invention I "will: proceed p to describe its construction and operation:

i Fig. l,` letters A, `A, are the knivesyB,

i `the double crank C,"`the upright levers to `which the knives are fastened, and act as hinges; D, the upright towhich* the levers C are attached;Y E, the uprights for steadying the knives` and `for keeping them together; F, the front` side of `the frame, in l which the crank B, is placed and between which it revolves; G,G,ithe feed rollers;

I-I, a ratchet in whicha pawl I) works;` I, bracerunning lengthwise of the box; J,le-

.ver resting onbrace I,.having its fulcrum on the same, and fastened to pawls, b, b; K, a cam lever `for"operating the feed mo- Fig.` Qis a side elevation. A, A, the ends of the knives where they i are attached to the crank; B, double crank, a, the handle;

i "F, F, the `posts forthe double crank to re` volve in; I, brace; J, lever rest-ing on brace l I; Z9, pawls for feeding; K, cam lever; L, L,

base of the frame;` M, spiral spring; N,

` the back uprights; O, the boX.

In operating my machine by revolving the crankV B, the knives are made to oscil-V late or `vibrate in a `vertical direction as shown 1n the red llnes c, c, and the recipro `cating motion is` given them behind, where p they are fastened at `C and operate in the arc of a circle as shown in the red lines d, d, giving to the knives each time theyvibrate ashear cut thereby making two shear cuts in each revolution of crank B,which is the best device for cutting straw, or other articles of food. And'as the vcrank revolves, the cam lever K operates on the lever J which moves the pawls b, `b which turn the ratchet lH, and rollers Gr, thereby feeding the material between the knives at the i proper time for them to cut it at each shear stroke given to the knives ascrank B revolves. A

Having described theconstruction and op-` eration of my machine, what I claim as new` anddesire to secure by Letters Patent, is:

1. Knives A, A, in combination with the doublecrank B, and lever @thereby giving to the knives an oscillatory reciprocating motion, by which means I obtain two 'shear cuts of the knives at each revolution of the double crank B, as herein described, and claimed. r

2. I claim the cam lever K andV crank B, in combination with lever J, and pawls b, b,

ratchet H, and feed rollers Gr, Gr, for lthe purpose of feeding the straw, or other material to the knives as set forth.
